Abstract

A spectacle lens, which is manufactured by additive manufacturing, includes interspersing first volume elements and second volume elements. The first and second volume elements are arranged on the grid points of a geometric grid to form a first sub-grid and a second sub-grid, respectively. The first sub-grid forms the first part of the spectacle lens having a dioptric effect for vision for a first object distance and the second sub-grid forms the second part of the spectacle lens having a dioptric effect for vision for a second object distance, which differs from the first object distance.
